Method and apparatus for acquiring information using device in idle state in wireless communication system
First Claim
1. A method of acquiring information related to a primary system in a wireless communication system, the method performed by a secondary entity of a secondary system and comprising:
- transmitting a request for the information to a multi-radio access technology (RAT) device supporting a primary RAT for the primary system and a secondary RAT for the secondary system when the multi-RAT device is in a radio resource control (RRC) idle state for the primary system;
starting a timer having a default value upon transmitting the request;
receiving a first response to the request from the multi-RAT device if the requested information is not acquired by the multi-RAT device before the timer expires, the first response indicating rejection of the request and a reason for the rejection;
reconfiguring the timer based on the first response; and
receiving a second response to the request from the multi-RAT device before the reconfigured timer expires, the second response indicating approval of the request and including the requested information.

Abstract
A method and apparatus of acquiring information on a primary radio access technology (RAT) system in a wireless communication system is provided. An entity of a secondary RAT system transmits a request for information on the primary RAT system to a multi-RAT device, and upon transmitting the request, starting a waiting timer which has a default value. If it is determined that the information on the primary RAT system cannot be acquired, by the multi-RAT device, until the waiting timer expires, the entity of the secondary RAT system reconfigures the waiting timer by a fixed value or a dynamic value.

9. A method of transmitting information related to a primary system in a wireless communication system, the method performed by a multi-radio access technology (RAT) device supporting a primary RAT for the primary system and a secondary RAT for a secondary system and comprising:
-
entering a radio resource control (RRC) idle state for the primary system; receiving a request for the information from a secondary entity of the secondary system while operating in the RRC idle state; starting a timer having a default value upon receiving the request; determining whether the requested information is acquired from a primary entity of the primary system before the timer expires; transmitting a first response to the request to the secondary entity if it is determined that the requested information is not acquired before the timer expires, the first response indicating rejection for the request and a reason for the rejection; and transmitting a second response to the request to the secondary entity before a reconfigured timer expires, the second response indicating approval of the request and including the requested information. - View Dependent Claims (10)
